I am trying to install a smart flood light that requires a neutral wire. Edit after initial post -> Using a multimeter, when the switch is turned on, the outside black wire reads 120v and the white 0. Both outside wires are 0 when the switch is turned off. (not sure if that means a neutral or not...)
In the switch box I can see a bundle of neutral wires, but I can't tell if the white wire to the outside of the house for the light is a neutral wire.
Can I install the light by simply hooking up the corresponding wire colors without knowing if it's a neutral? The house was built in 2005.
